| New 16-bit dsPIC Digital Signal Controller Goes to Production Microchip Technology has announced that it continues the production rollout of its 16-bit product portfolio with a new dsPIC Digital Signal Controller (DSC) that offers designers a performance speed of 30 million instructions per second (MIPS), self-programming capabilities via Flash memory, and industrial and extended temperature ranges. The dsPIC30F6015 DSC features an advanced pulse-width modulation (PWM) peripheral designed for power-conversion, motor-control and lighting applications, an associated 1 million samples per second (MSPS) 10-bit analog-to-digital (A/D) converter, 144 Kbytes of Flash program memory and can operate at full speed using an internal oscillator (no crystal required). This DSC is offered in a 64-pin TQFP package, and is ideal for applications that drive power FETs and require advanced algorithmic processing. Microchip's dsPIC DSCs are offered in two families - the dsPIC30F and dsPIC33F. The dsPIC30F may be preferable for applications that favor any of the following attributes: - Wide operating voltage range (2.5 to 5.5V) - 5-volt operation to maximize analog noise immunity or to minimize voltage translation logic - Lowest power consumption in the "power down" mode of operation - Integrated, high-endurance on-chip EEPROM The 3.3-volt dsPIC33F family may be preferable for applications that favor any of these attributes: - Larger memory configurations (Flash and/or RAM) - Lower operating power consumption - Maximum performance - Lowest cost for larger memory configurations. The dsPIC30F6015 is part of Microchip's Motor Control and Power Conversion portfolio. The Motor Control and Power Conversion portfolio is supported with both dsPIC30F and dsPIC33F family devices. The dsPIC30F6015 incorporates Microchip's Enhanced Flash self-programming capability, which permits a remote upgrade to the Flash program memory, allowing code revisions in end users' applications. Additional key features include: - 144 Kbytes of Flash Program Memory, which can withstand typically 100.000 erase/write cycles and has 40-plus years of data retention over a wide operating-voltage and temperature range - 8 Kbytes of SRAM - 4 Kbytes of high-endurance EEPROM (1 million erase/write cycles typical) - 8 output PWM, complementary or independent modes, 4 duty-cycle generators, programmable dead time - 10-bit A/D converter with up to 16 signal channels, 1 MSPS, 4 sample and holds for simultaneous sampling, and trigger option from advanced PWM - Quadrature Encoder Interface - Five 16-bit timers - Eight standard PWMs - Two of each: CAN, SPI and UART peripherals - One I2C peripheral All dsPIC30F DSCs use the same MPLAB Integrated Development Environment (IDE) shared by Microchip's PIC microcontroller family. Additionally, the dsPIC30F is supported by Microchip's high-performance development systems, including: MPLAB C30 C Compiler, MPLAB SIM 30 Software Simulator, MPLAB ICD 2 In-Circuit Debugger and MPLAB Visual Device Initializer. write your comments about the article :: © 2006 Computing News :: home page |
